How homogeneous is the air velocity and temperature distribution between cabinets?
Home  >  Services  >  Datacenter


Datacenters, which have a direct share of almost 3% in electricity consumption, are known to increase these demanding attitudes and to have a quarterly increase. We also know that cooling loads account for about 50% of the electricity consumption in system operation. When we consider these, the most reasonable approach is to ensure that the design works efficiently and with the least loss.


Data Center cabinet layout and air conditioning principle overview

Mechanical design teams sometimes with precision air conditioners, sometimes VRF or VAV and so on. systems with cooling fictions. It is essential to make the highest heat transfer homogeneously with the movement of air. The critical issue that the designer demands from us is to minimize the pressure losses and not to increase the ambient temperature above the specified degree and to ensure that the air velocities and general distribution are as homogeneous as possible. Heat generation amounts are determined for each rack cabinet and device type. It is important for approval during commissioning that the air coolant that can be given to the space and the air collected from the system suction vents do not exceed the critical values of the suction temperatures.

Homogeneous distribution of air velocities between Data Center cabinets is important

Each project type differs in itself. For example, the placement, types, fan models or grid structures of devices in cabinets are sometimes different. The most critical support provided by the calculation tools is that every detail can be simulated with modeling detail. For example, when an underfloor system is constructed, numerical modeling of grill permeability can be done, and sometimes the grills can be analyzed with actual measurements. The front and rear grille details of the cabin, the working pressure information of the air conditioners (should be analyzed together with the variable flow / pressure values) or the details of the transport of air without pressure loss for homogeneous distribution should be examined.

Fluid analysis methods, which can be used to critique the performance of the system, have also become necessary in a short time to answer whether the first design will work or not. The real opportunity presented here is to create unique designs with experience and competence, being aware that there are no geometrical or physical limitations in solving the heat and flow problem in software.
